Abstract

The motor vehicle has a manually operated mechanical hand brake whose operating element is connected to an electric switch for detecting its operated or not operated state.. The switch randomly activates and deactivates a parking brake function implemented by the electronically regulated braking system, which can be activated by first pulling and then releasing the hand brake within a defined time window.

Description

Die Erfindung betrifft ein Kraftfahrzeug mit einem elektronisch regelbaren Bremssystem nach dem Oberbegriff des Patentanspruchs 1.The The invention relates to a motor vehicle with an electronically controllable Brake system according to the preamble of patent claim 1.

Derartige Kraftfahrzeuge sind hinreichend bekannt. Mit den elektronisch regelbaren, meist hydraulisch betätigten Bremssystemen werden zum einen fahrdynamische Bremsregelungsfunktionen, wie z. B. ABS-, ASC- oder DSC-Systeme, und zum anderen komfortbezogene Bremsassistenzsysteme, wie z. B. manuell oder automatisch aktivier- und deaktivierbare Feststellbremsfunktionen (auch Anfahrassistent oder Hillholder genannt), durchgeführt. Beispiele für derartige bekannte Systeme sind in den Druckschriften DE 199 50 162 A1 , DE 196 11 359 C1 oder EP 0 825 081 B1 zu finden. Tendenziell werden Feststellbremsfunktionen vermehrt automatisch aktiviert und deaktiviert, wodurch die Eingriffsmöglichkeiten des Fahrers eingeschränkt werden (z.B. DE 198 38 886 A1 ).Such motor vehicles are well known. With the electronically controllable, mostly hydraulically operated brake systems, on the one hand, dynamic vehicle brake control functions, such as. B. ABS, ASC or DSC systems, and on the other comfort-related brake assistance systems such. B. manually or automatically activated and deactivated parking brake functions (also called start assist or hill holder) performed. Examples of such known systems are in the publications DE 199 50 162 A1 . DE 196 11 359 C1 or EP 0 825 081 B1 to find. Parking brake functions tend to be activated and deactivated automatically, which limits the driver's options for intervention (e.g. DE 198 38 886 A1 ).

Weiterhin sind in den meisten Fahrzeugen unabhängig von den elektronisch regelbaren Bremssystemen noch manuell zu betätigende mechanische Handbremsen vorhanden, deren Bedienelement (meist ein Hebel) mit einem elektrischen Schalter zur Erfassung des betätigten bzw. des unbetätigten Zustands der Handbremse verbunden ist. Das Signal dieses Schalters wird bereits in vorhandenen elektronischen Antriebssteuergeräten ausgewertet.Farther are independent of the electronically controllable in most vehicles Brake systems still manually operated mechanical hand brakes available, the control element (usually a lever) with an electric Switch for the detection of the operated or the unactuated state the handbrake is connected. The signal from this switch is already evaluated in existing electronic drive control units.

Es ist Aufgabe der Erfindung, ein bremsbezogenes Assistenzsystem für den Fahrer mit kostengünstigen Mitteln bei gleichzeitiger Erhöhung der Eingriffsmöglichkeiten zu verbessern.It is the object of the invention, a brake-related assistance system for the driver with inexpensive Mean while increasing the possibilities of intervention to improve.

Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst. Der Gegenstand des abhängigen Anspruchs ist eine vorteilhafte Weiterbildung der Erfindung.This Object is solved by the features of claim 1. The Subject of the dependent Claim is an advantageous development of the invention.

Erfindungsgemäß wird bei einem Kraftfahrzeug mit einem elektronisch regelbaren (z. B. elektrisch, pneumatisch oder hydraulisch betätigten) Bremssystem und mit einer manuell zu betätigenden mechanischen Handbremse, deren Bedienelement mit einem elektrischen Schalter zur Erfassung des betätigten bzw. des unbetätigten Zustands der Handbremse verbunden ist, der mit dem Bedienelement der Handbremse verbundene elektrische Schalter zur willkürlichen Aktivierung und Deaktivierung einer mittels des elektronisch regelbaren Bremssystems durchführbaren Feststellbremsfunktion verwendet.According to the invention a motor vehicle with an electronically controllable (e.g. electrical, pneumatically or hydraulically operated) braking system and with a manually operated mechanical Handbrake, the control with an electrical switch to record the actuated or the unactuated State of the handbrake is connected to the control element of the Handbrake connected electrical switches for arbitrary Activation and deactivation of an electronically controllable Brake system feasible Parking brake function used.

Unter dem Begriff Feststellbremsfunktion ist beispielsweise auch eine Parkbremse, eine Anfahrassistenzfunktion oder eine Hillholder-Funktion zu verstehen.Under the term parking brake function is also, for example Parking brake, a start-up assistance function or a hill holder function to understand.

Vorzugsweise wird die Feststellbremsfunktion durch ein erstmaliges Anziehen und wieder Lösen der Handbremse innerhalb eines ersten vorgegebenen (kurzen) Zeitfensters (etwa im Sekundenbereich) aktiviert und durch ein nachfolgendes Anziehen und wieder Lösen der Handbremse innerhalb eines zweiten (kurzen) vorgegebenen Zeitfensters (etwa im Sekundenbereich) deaktiviert. Das erste vorgegebene Zeitfenster kann gleich dem zweiten vorgegebenen Zeitfenster sein.Preferably the parking brake function is activated by first applying and releasing the Handbrake within a first specified (short) time window (approximately in the range of seconds) and activated by a subsequent one Tighten and loosen again the handbrake within a second (short) predetermined time window (approximately in the seconds range) deactivated. The first specified time window can be equal to the second specified time window.

Der Erfindung liegt die Erkenntnis zugrunde, dass der eigentlich der Handbremsfunktion zugeordnete Schalter multifunktionell einer anderen Funktion zugeordnet werden kann. Diese andere Funktion in Form einer Feststellbremsfunktion ist zwar von der manuell zu betätigenden mechanischen Handbremsfunktion entkoppelt, jedoch sind die Funktionen in der Weise verwandt, dass vom Fahrer keine Bedienung entgegen seinem Willen zum „Feststellen" des Fahrzeuges verlangt wird. Die Handbremse kann auch weiterhin ganz im üblichen Sinne betätigt werden. Durch die multifunktionale Verwendung des Handbremsenschalters können kostenintensive Zusatzschaltelemente eingespart werdenThe Invention is based on the knowledge that the Handbrake function assigned switches multifunctional to another Function can be assigned. This other function in the form of a Parking brake function is of the manually operated mechanical handbrake function decoupled, however, the functions related in such a way that the driver does not oppose any operation his will to "lock" the vehicle becomes. The handbrake can still be used as usual Senses operated become. Thanks to the multifunctional use of the handbrake switch can costly additional switching elements can be saved
